COC Methods for Additional Geometrical Constraints,cannot handle such large numbers of elements, the analysis capability of these is expected to keep on increasing in the foreseeable future. The COC algorithm, therefore, represents an optimizer that . in the optimization of large structural systems.

Mixed Elements in Shape Optimal Design of Structures Based on Global Criteria,to the optimal shape design of two dimensional elastic structures, selecting the compliance as the objective function to be minimized and the initial volume as constraint. The advantages and disadvantages of the mixed elements are discussed with reference to applications.

Mathematical Programming Techniques for Shape Optimization of Skeletal Structures,imum layout to be designed. The third type of method includes those which allow for topological considerations at certain points during the design process and generally keeps the design variables in two separate groups. The paper discusses the way in which each of the mathematical programming methods has been applied to these approaches.

In optimal elastic design, however, which is to be discussed in this chapter, it is usually necessary to resort to numerical methods because the equations involved are too complicated for an analytical treatment. Moreover, whilst in optimal plastic design (Fig. 6) we had a half rea
